refresh

问题 Basically I am practicing NodeJs/MongoDB by making a simple blog app. I am using the .find() method to final all the saved blogs on the db , and then running it through a loop to post it on the main page. That method is called every time the page is refreshed, so how do I stop it from being called to avoid automatic reposts? exports.getBlogEntries = function() { Entry.find(function(err, entries) { if (!err){ for(i = 1; i < entries.length; i++ ) { list.push(entries[i]); } } }); return list; };

问题 I noticed that when I run a functional test with PhpUnit, if there is a modification in the database, it is done. However, if I'm in the middle of my test and want to recover the record that was changed, it comes back to me in its old version, which is very problematic. For example, if I have a test in which: I collect a certain item I activate it (therefore, modification in the database of its enable property) via a URL of a controller I want to check that it is active I retrieve it from the

问题 I have a page that grabs content from a XML file through a Jquery AJAX call. The problem is it will update the content from the XML file on a refresh for every browser except IE.

These are the issues I'm facing: 1) at first, if the articles to show is set to 10, then if i go to settings and change it to 2, then the last 8 articles are disappearing but the white space /gap is not

问题 I've been looking for mechanism to update the model of a Route, and has the Component (called from within the template associated with that route) reacts to that event, and re-render itself. So I have the index template like this (I pass in the model of the IndexController, which to my understanding is just a proxy to IndexRoute -- I don't have IndexController defined, by the way): <script type="text/x-handlebars" id="index"> Below is the bar-chart component <br/> {{bar-chart model=model}} <
